The Amazons issue will be fixed in the next release (due sometime in Late August if the Apple Approval Gods are with us ).

For the Sorcerers, a simple work around is to remember to use your power before your final conquest. Usually (agreed, not always, but often) this makes no difference as to which unit you could use your Sorcerer Power on. We will also work on a fix (but I doubt it can be in the upcoming release, as there's already a lot on our plate there).
